Verilog is a Hardware Description Language (HDL) used to model digital logic. The values of signals can be written out to a Value Change Dump (VCD) file while simulating logic circuits. The syntax of the VCD *text file* is described in the documentation of the IEEE standard for Verilog, ...
[Mark] starts a post from a bit ago with: “… maybe you have also heard that SystemVerilog is simply an extension of Verilog, focused on testing and verification.” This is both true and false, depending on how you look at it. [Mark] thenexplains what the differences are. It’s a ...
The design process of FPGAs involves using hardware description languages (HDLs) such as Verilog or VHDL. An HDL allows engineers to describe the structure and behavior of the electronic circuit and system design. Applications of FPGAs FPGAs are utilized in a wide range of applications due to ...
What Is HDL Verifier? Test and verify Verilog®and VHDL®designs for FPGAs, ASICs, and SoCs with HDL Verifier™. Verify RTL with testbenches running in MATLAB®or Simulink®using cosimulation with HDL simulators. Use these same testbenches with FPGA and SoC development boards to ...

Why is UVM so important? SystemVerilog provides the base language features to build testbenches but doesn’t lay out a methodology/process for verification. It’s the nails, screws, hammer, and screwdriver, but has no instructions. UVM takes proven methodologies from both the hardware and softw...
A function shall return a single value; a task shall not return a value. Verilog is a hardware description language, meaning that various blocks of code directly map into hardware. Therefore, the designers must always have in mind the circuit they want to implement, not the program they want...
A memory compiler that creates the correct memory size for a given design is an example of this process. Descriptions of digital circuits expressed in high-level languages such as Verilog are automatically “compiled” into the logic elements needed to implement these functions. This is called ...
